There is nothing in the documents that require DVCMC to bank newly-purchased points "late"; instead the documents allow it. It would be perfectly possible for them to tell you: "Here are your 2024 points, you have until the end of August 2025 to use them, subject to availablity."
Will they do that? Almost certainly not. But it is important to remember that they can. Always confirm your plans with your Guide before your 10-day rescission period expires.
I like the two week buffer, because it gives one a little extra room in case someone somewhere drops the ball. I also get to the airport on the early side.
